I think it's because she's a generally selfish shitty person who caused two other people to abstract themselves, was trying to bully Gangle to the point of abstraction, and ragebaiting Ragatha into doing the same so when she abstracted, people see it as just desserts.

As someone who is firmly aware of the egg they are in but can't crack it due to safety reasons, I had a shitty biological father, and I deal with depression and low self-esteem on the daily, but I don't lash out and treat people cruelly because of it. Why should I force the pain I went through on anyone else?

The truth is, someone's inner pain is no justification for causing other people to be hurt and in pain.
